/**
   This file contains the definition off all builtin items
   It is parsed with the normal .slint parser, but the semantic.

   `_` means that that this is a langtype::NativeClass with no parent.
   Exported components are added to the as BuiltinElement.

   comments starting by `//-` have some meanings

   Properties with two way bindings (aliases) are deprecated in favor of the property they point to

   Properties can have default binding which must be an expression without any reference to
   another properties. These binding will be then set by the compiler.
   `output` property mean that the property can be modified by the native Item,
   otherwise it is assumed the native item don't write to that property.
